ZEL'DOVICH, YAKOV BQRISQVICH (Physicist) 



Y. B. Zel'dovich was born March 18, 1914. He studied at 

 Leningrad University. In 1931 he began working at the Institute 

 of Chemical Physics of the U.S.S.R. Academy of Sciences. He 

 was elected Corresponding Member of the U.S.S.R. Academy of 

 Sciences in 1946 and Academician in 1958. In 1943 he was 

 awarded a Stalin Prize. 



Zel'dovich examined the statistics of heterogeneous surfaces 

 based on the measurement of the adsorption isotherm. In the 

 period 1935-1939 he and associates ascertained the mechanism 

 of nitrogen oxidation during an explosion. Together with Yu. B. 

 IChariton, Zel'dovich proposed a calculation of the chain re- 

 action in uranium fission in 1939-1940. In 1938-1943, he and 

 D. A. Frank- Kamenetskii worked out a theory of the flame 

 propagation and proposed a mechanism for chemical reaction 

 in a shock wave.
